You can see the shoes and the bottoms here. Probably the best for paintball, as they have actual treads that can help you with grip for running on grass, turf, and so on, would be the Treks, Treksports (Both have the same bottom), and Spyridon. Everything else is going to be pretty smooth bottoms, and you won't really get much of any traction wearing them on any field. Unless it was concrete or asphalt or the like.
